CVE-2026-85694: LaVague 0.2.35 Remote Code Execution via eval extraction
LaVague 0.2.35 contains a remote code execution vulnerability in PythonFromMarkdownExtractor.extract_as_object that evaluates untrusted language model output derived from web page content. Attackers can inject malicious Python code through web pages using indirect prompt injection to execute arbitrary code on the operator's host without review.
Security readout for executives and security teams
Plain-English summary
LaVague 0.2.35 may execute Python supplied indirectly through hostile web content. A malicious page can influence language-model output, which the affected extractor evaluates on the operator’s computer. Successful exploitation could compromise the confidentiality, integrity, and availability of that host.
Executive priority
Treat exposed LaVague 0.2.35 automation as an immediate containment and remediation priority, especially on hosts holding credentials or production access. Prioritize inventory, isolation, and vendor-guidance review. The critical impact warrants urgency even though active exploitation is not established.
Technical view
The flaw is in PythonFromMarkdownExtractor.extract_as_object. It evaluates untrusted language-model output derived from web content, creating a CWE-94 code-injection path. Exploitation requires indirect prompt injection and successful manipulation of model output; the supplied CVSS 4.0 score is 9.2.
Likely exposure
Exposure is most likely where LaVague 0.2.35 processes attacker-controlled or untrusted webpages and invokes the affected extractor. The bundle does not establish whether other releases are affected, despite inconsistent affected-version metadata, so inventories require careful verification.
Exploitation context
The source bundle describes a viable remote-code-execution condition, but does not report observed exploitation. The CVE is not identified as KEV. Attack complexity is rated high and requires a prompt-injection condition, yet no privileges or user interaction are reflected in the supplied vector.
Researcher notes
The core trust-boundary failure is evaluation of model-generated text influenced by webpage content. The supplied evidence identifies version 0.2.35, while structured affected data lists “0” with default unaffected status; this inconsistency limits version-range conclusions. No fixed release or vendor-endorsed workaround is supplied.
Mitigation direction
Identify and suspend LaVague 0.2.35 workflows that process untrusted web content.
Avoid using PythonFromMarkdownExtractor.extract_as_object until vendor guidance is reviewed.
Run unavoidable automation in isolated, least-privileged environments without sensitive credentials.
Check the project issue and advisory for an official patch or safe upgrade.
Restrict outbound access and secrets available to affected automation hosts.
Validation and detection
Inventory installed LaVague versions and locate deployments running 0.2.35.

CWE-94: Code execution behavior lookup
Code execution and unsafe deserialization weaknesses often justify reviewing execution behavior and process telemetry. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
The CVE wording references code or command execution, so execution technique review may help defensive triage. This is a Glexia inferred lookup path, not an official MITRE, ATT&CK, or CVE Program mapping.

Improper Control of Generation of Code ('Code Injection')
Improper Control of Generation of Code ('Code Injection') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
